Which of the following is a Platoon Sergeant duty?

• A. Platoon Leader
• B. Platoon Sergeant
• C. Chalk Leader
• D. Company Commander

Answer: (B)

At the platoon level, the Platoon Sergeant is the senior enlisted leader who directly supports the platoon leader by guiding training, readiness, discipline, and welfare of the soldiers. This role acts as the primary link between the platoon leader and the enlisted soldiers, helps plan and supervise operations, and stands in for the platoon leader when needed. That makes it the duty associated with the platoon level and its enlisted leadership responsibilities.

Placing the other roles in context helps confirm why this is the fit: the Platoon Leader is the officer in charge of the platoon and makes command decisions. The Chalk Leader leads a specific chalk of soldiers during airborne or air assault operations, a specialized task not typical of every platoon duty. The Company Commander oversees multiple platoons and commands at the company level, a higher echelon than the platoon.
